Critical thermodynamics of two-dimensional N-vector cubic model in the five-loop approximation
P. Calabrese, E. V. Orlov, D. V. Pakhnin +1
The critical behavior of the two-dimensional N-vector cubic model is studied within the field-theoretical renormalization-group (RG) approach. The beta-functions and critical expon…
Critical behavior of two-dimensional cubic and MN models in the five-loop renormalization-group approximation
P. Calabrese, E. V. Orlov, D. V. Pakhnin +1
The critical thermodynamics of the two-dimensional N-vector cubic and MN models is studied within the field-theoretical renormalization-group (RG) approach. The beta functions and…
Nonlinear susceptibilities of a weakly-disordered uniaxial ferromagnet in the critical region
D. V. Pakhnin, A. I. Sokolov, B. N. Shalaev
For the three-dimensional random Ising model, the effective sextic coupling constant v_6 and the nonlinear susceptibilities of the fourth (chi_4) and sixth (chi_6) orders are calcu…
Renormalization group and nonlinear susceptibilities of cubic ferromagnets at criticality
D. V. Pakhnin, A. I. Sokolov
For the three-dimensional cubic model, the nonlinear susceptibilities of the fourth, sixth, and eighth orders are analyzed and the parameters δ^(i) characterizing their reduced ani…
Five-loop renormalization-group expansions for the three-dimensional n-vector cubic model and critical exponents for impure Ising systems
D. V. Pakhnin, A. I. Sokolov
The renormalization-group (RG) functions for the three-dimensional n-vector cubic model are calculated in the five-loop approximation. High-precision numerical estimates for the as…
